You can tell the age of a skeleton by looking at:
O1) the length of the femur
O2) the shape of the pelvis
O 3) the number of fused bones
O4) the color of the bones
Answer:
Calculating the age of a skeleton can be done by looking at the number of fused bones (option 3).
Explanation:
The calculation of skeleton bone age takes into account the complete ossification of bones, which occurs at various stages of human development.
In childhood, the epiphyses or ends of long bones are not completely ossified but are formed by cartilage, due to the process of growth. When development is achieved, the growth nuclei and cartilage disappear.
Bone age is a reliable parameter for calculating chronological age, as they are quite approximate.
The other options are not correct because:
1. The length of the femur is useful for calculating height.
2. The shape of the pelvis helps to differentiate the sex.
4. The color of the bones is not a useful parameter to calculate the age of the skeleton.

1. Nitrogen fixation: Nitrogen fixation occurs when (a) ___________ converts N2 gas into (b) _________________________ that living things can take up.
2. Ammonification: In this step, bacteria in soil or fungi will convert nitrogen into _____________________________
3. Nitrification: A 2-step process:
Step 1: Soil bacteria converts (a)_______________________ into (b)___________________
Step 2: Soil bacteria then convert nitrite ions into (c)_____________________________
4. Denitrification: In this process (a)__________________________ are converted to (b)_________________ gas, which are then released to the atmosphere.
5. Assimilation: This occurs when ___________________________________________.
Answer:
Nitrogen fixation occur when nitrogenase convert N2 into ammonia gas that living thing can take up.
Ammonification bacteria in soil or fungi will convert nitrogen into ammonia compound.
3. Nitrification.
Soil bacteria converts ammonia to nitrite.
Soil bacteria then convert nitrite ions into nitrate.
4. Denitrification in this process , nitrate is converted to nitrogen gas, which are then released to the atmosphere
Assimilation occurs when minerals and vitamins are absorbed in the food by the intestine.
Explanation:
Nitrogen fixation is the process where nitrogen is fixed and made available by living things in which nitrogenase convert nitrogen to ammonia.
Ammonification is the process by which organic nitrogen is converted to ammonia compounds by bacteria and fungi
Nitrification is the process where nitrifying bacteria convert ammonia to nitrite and then nitrite to nitrate.
Denitrification is the process where nitrate is reduced or converted to nitrogen gas.
Assimilation is the process of absorbing vitamins and minerals from food by the intestine.
If an organism is said to reproduce asexually, how would the offspring resemble the parent organism?
Answer:
It would resemble it through its genetic features.
Explanation:
Answer: Asexual reproduction produces offspring that are genetically identical to the parent, whereas sexual reproduction produces a similar, but genetically unique offspring. In sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote (Figure below).

Which tissue(s) is/are prone to injury and heal poorly because the ratio of extracellular matrix to cells is very high?
A. Cartilage.
B. Joint Capsule.
C. Ligament.
D. Bone.
E. Tendon.
Answer:
The correct answer is option E "Tendon"
Explanation:
Tendon associate muscle to bone, conveying probably the most noteworthy powers experienced by any vertebrate tissue, as they encourage development and give skeletal dependability.
The proportion of matrix to-cells in Tendon is hence among the most noteworthy of any vertebrate tissues; in this way understanding grid structure and association, and how cells communicate with lattice, is critical to understanding the capacity, homeostasis and fix of Tendons. While huge advances in our comprehension of Tendon work have been made, major unanswered inquiries stay, for example, how cells build up the Tendon grid and how the matrix association clarifies the mechanical properties of Tendon. This information is an essential for the advancement of novel methodologies to improve Tendon healing in the treatment of tendinopathies.

What causes surface currents to move? Do you think surface currents have an effect on deep ocean currents?
Answer:- Surface is primarily driven by wind (friction from wind transfers energy and momentum to surface water)
- Deep is slower, driven primarily by density (salinity and temperature) differences
- Thermocline: dramatic temp drop 50 m from surface bc sun can't shine
- Halocline: dramatic gradient in saline, increase as it deepens
- Pycnocline: resulting change in density (50-1000)

If a species has a 2n number of 18, how many autosomes would their SOMATIC cells have?
Answer:
If a species has a number of chromosomes 2n = 18, then its somatic cells have 16 autosomes.
Explanation:
Somatic cells are diploid, that is, they have the complete chromosomal charge, and it is represented as 2n. In organisms with sexual reproduction the chromosomes are divided into autosomes and sex chromosomes, which are 2.
If a species has a number 2n = 18, it means that its somatic cells have 18 chromosomes, of which 16 are autosomes and 2 are sex chromosomes. Autosomes contain the structural and functional characteristics of an individual, while the sex chromosomes determine sex.
explain how precipitation affects the phosphorus cycle
Answer:
Disrupts the nitrogen cycle by contaminating the groundwater and making it more difficult for the plants to absorb the nitrogen and causes the phosphorus cycle to accelerate, resulting in an excess of phosphorus in water and soil.
Explanation:
The precipitation affects the phosphorus cycle in many ways where the soil erosion will take place if the precipitation happens then the weathering of rocks along with the soil getting off will make the nutrients loss in the soil.
What is the cycle of rain called as ?
The cycle of the rain is called as water cycle where the evaporation along with the condensation takes place.
If the precipitation level in the atmosphere is increased then in this case it will increase the transportation of phosphorus along with the other nutrients into soil along with the water sources and the coastal areas as well.
The main reasons of such scenario is because of the deforestation, loss of habitat by the continued invasion of human activities in the natural resources. The reduction of nutrients loss in soil makes an huge impact over the phosphorus cycle.

How is the space shuttle able to leave earth's surface?
PLEASE TELL ME IS ITS A, B, C, OR D
Answer: A
Explanation:
The shuttle needs to go up in order to get into space, this means they need to create a force greater then gravity because if they didn’t the shuttle wouldn’t be able to accelerate upwards
The space shuttle is able to leave Earth's surface when the space shuttle engine creates an upward force that is greater than downward force of gravity.
The force of gravity pulls every towards the center of the Earth, to overcome this force of gravity the space shuttle will create an upward force that is greater than force of gravity.
The upward force created by the space shuttle engine must overcome the downward force of gravity on the space shuttle.
To overcome the force of gravity, the space shuttle engine speeds upwards with a velocity known as escape velocity.
Thus, we can conclude that the space shuttle is able to leave Earth's surface when the space shuttle engine creates an upward force that is greater than downward force of gravity.
